The PIC16F628A is an 18-pin Flash-based member of the versatile PIC16F627A/628A/648A family of low-cost, high-performance, CMOS, fully static, 8-bit microcontrollers.
PIC16F628A is a CMOS FLASH-based mid-range 8-bit microcontroller that comes with an 18-Pin package, out of which, 16 pins can be used as I/O pins. This microcontroller has 4 Mhz of the internal oscillator with 128 bytes of EEPROM data memory, packed with a single Capture/Compare/PWM, and a USART module with 2 comparators.
All PIC® microcontrollers employ an advanced RISC architecture. The PIC16F628A has enhanced core features, an eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two-stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available, complemented by a large register set. PIC16F628A microcontroller typically achieves a 2:1 code compression and a 4:1 speed an improvement over other 8-bit microcontrollers in their class.
PIC16F628A devices have integrated features to reduce external components, thus reducing system cost, enhancing system reliability and reducing power consumption. The PIC16F627A/628A/648A series fits in applications ranging from battery chargers to low-power remote sensors. The Flash technology makes customizing application programs (detection levels, pulse generation, timers, etc.) extremely fast and convenient. The small footprint packages make this microcontroller series ideal for all applications with space limitations. Low cost, low power, high performance, ease of use and I/O flexibility make the PIC16F627A/628A/648A very versatile.
